.Be it known that l, Janome ll, GEORGE, a citizen of the United States, residing at Worcester, in the county of llorcester and Commonwealth of lllassachusetts, have invented a new and useful improvement in a Housing' for ltollingdldills, of which the fol lowing, together with the ccoinpanying drawings, is a specification. v

'lhe present invention relates: to -thecon-I struction of a pinion housing designed to contain the pinions used for driving; therolls of a rolling mill, and has particular reference to the provision of suitable devices for retaining the hearings for such pinions in position, and at the same time affording a means for facilitata'ogg the disengagement oi" the pinions from their connections with the rolls, in order to permit the removal of the bearings .and the pinions from the housing.

The invention is set forth in detail in the following; description, reference being had to the accoinpanyin' drawings, :in which-v Figure l is anen View of a pinion-lionsingr embodying my invention.

Fig. 2 is a view in side elevation of a por tion of the housing shown in Il, and

also illustrating the couplings between the .pinions and the rolls.

and

Fig. 4 is a perspective View o logger retaining plate, for the bearinss oli the pinions.

The housing, designated a whole. oy the numeral 1 may he of ordir ry construction, 'providing end walls 9;, 2 rising` from a base As shown in the drawings, each end wall is centrally recessed from, the top, as indi`v cated by the dotted lines Il, l, to receive a hearing 5 .tor the shaft 6 of the lower pinion, and a snperposed hearing 7 for the shz'iit 8 of the upper pinion. The usual or cover spans the space between the Walls 2, and closes the upper ends oi?y 4i, l in the usual manner, thereby retaining the hea-r11 5 "and I therein.

as shown, each of the hecrii'igs 55, which may he oli any vvoll-lrnown construction, pro vides de iianges l0, edges oit the recess 4l, and seating against the outer lace of the Wall El, thereby pre-- venting inward displacement: of the hearing.

The pinion shafts 6 and 8 project through the usual central bosses 11, 11 of the bearings, and are groovod at their ends, as shown at 12, Fig, l, :lj'or operative connection to the shafts o the rolls, not shown, hy means of the usual sliding coupling collars 15, Figs. 2 and 3,

The bearings 5 and 7 are secured against outward displacement by means of a pair of' dogs or retaining plates, 16 one of which is shown detached in 4.' Each dog 16 provides a pair oi spaced apertured ears l?, through which loosely pass bolts 18, 18, prothe Wall 2 near-the vertical` edges of the flanges of the be" rings 5 and 7. Each earhas a lng 19 formed on its inner surface, the pair of dogs thereb Y providing contact with the flange l0 at two points on each side, near the corners of said fiange. Each dog 1.6 provides an. inwardly turned tongue Q0, adapted to bear at a single point against the face ofvf'all 2, when the dog is in position. Nuts2l.,- -when screwed down on the bolts 18 against the face force the latter into m three-point engagment with the flange 10 and wall 2, the loose passage pi' the bolts through ,the apertures oithe ears 17 permitting xfree movement of the dog; to carry each lug 19 against the face et' flange 10, and to carry the end otE tongue 20 into Contact with the face of Wall 2. In thisl manner, each side of the hearing is pressed lirmly inward against the face of wall 52 and. held against displacement, until the nuts 2i are removed, permitting the reand the Withdrawal of the bearing from the housing..

.Each dog 16 provides an outwardly extending projection'22, disposed between the ears l? thereof. This projection 22 is shouldered at an intermediate point, 28, proa ifi-ding: a fulcrum to support a lever or crowbazf, when itis desired to pry the correspond ing collar 15 outwardly, in order to d1sconnect the pinion shaft 6 or 8 from the correspending roll shaft, not shown. i One or more ol said intermediate shoulders may he provided, to permit the fulcrnm of the lever to he shifted, as the collar is graolnally moved outwardly. The end of the projection 22 is suitably notched, as at 24, to provide an additional fulcrum point for thelever, in. ohtaining the final 115, 1in' this manner the dogs 16 provide a means for facilitating the disengagement of the dog,

gli

movement of the collar Y of the rolls from the pinions, in addition to their function as retaining devices for the bearings 5 and 7.

As shown in Figs. 1 and 2, the base 3 provides,I beneath the outer ends of the bearings 5 and 7, a trough or other receptacle open at the top to catch the oil and grease which overioivs from the bearings 5 and 7, thereby preventing the spreading of lubricant on the floor ofthe mill.

With a housing of the type shown, the bea-rings are removable through the top thereof, as well as longitudinally; it will be seen that by merely loosening the nuts 21 on the bolts 18, without removing the retaining dogs 1G, the bearings 5 and 7 can be withdrawn through the top of the housing.

1t will be further seen that each removable retaining member 1G is in effect a lever, reacting, through the tongue 20 against the face of the housing. The disposition ofthe projections 22 on said members 16, instead of on the housing, affords a decided advantage; if made integral with the housing, these projections could not he replaced, if broken off. vBut vvith -the present arrangement, a new retaining dog can be easily substituted, at small cost, if a projection 22 becomes broken olf.

l. The combination, with a housing of a bearing supported therein, a shaft in said bearing and a coupling slidable on. said shaft, and removable means independent of saidy housing, providing a plurality of successive fulcrum points for the application of a lever to slide said coupling along said shaft.

2. The combination with a housing, of a bearing supported therein, a retaining device for said bearing adapted to make threepoint contact with said bearing and said housing, and means for restraining said device against movement away from said housing intermediate its points of Contact with said housing and bearing respectively.

3. The combination with a housing, of a bearing supported therein, a retaining device for said bearing adapted when in position to contact with said bearing at two points and with said housing at a single point, whereby to provide a three-point ougagement for said device, and means disposed intermediate the points of contact with said housing and bearing respectively for restraining said device against movement away from said housing. 4. The combination, and a coupling slidable on said shaft, of a retaining member for said bearing, providing a plurality of successive fulcrum points for the application of a lever to slide said coupling along said shaft.

5. The combination, with a shaft, a bearing, and a coupling slidablc on said shaft, of a retaining member for said bearing, and a projection on said retainingr member providing a series of successive axial supporting points for a lever, to slide said coupling along said shaft.
